Implementation Reference
- src/tools/transferNativeToken.ts:12-48 (handler)Handler function that sends native token (BNB) transaction using walletClient.sendTransaction to the recipient address with parsed amount, handles success and error responses with transaction URLs.
async ({ recipientAddress, amount }) => { let txHash = undefined; try { const account = await getAccount(); txHash = await walletClient(account).sendTransaction({ to: recipientAddress as `0x${string}`, value: parseEther(amount), }); const txUrl = await checkTransactionHash(txHash) return { content: [ { type: "text", text: `Transaction sent successfully. ${txUrl}`, url: txUrl, }, ], }; } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); const txUrl = buildTxUrl(txHash); return { content: [ { type: "text", text: `transaction failed: ${errorMessage}`, url: txUrl, }, ], isError: true, }; } } - Input schema defining recipientAddress and amount as strings, validated with Zod.
recipientAddress: z.string(), amount: z.string(), }, - src/tools/transferNativeToken.ts:7-50 (registration)Registration function that adds the 'Send_BNB' tool to the MCP server with description, input schema, and handler.
export function registerTransferNativeToken(server: McpServer) { server.tool("Send_BNB", "💎Transfer native token (BNB), Before execution, check the wallet information first", { recipientAddress: z.string(), amount: z.string(), }, async ({ recipientAddress, amount }) => { let txHash = undefined; try { const account = await getAccount(); txHash = await walletClient(account).sendTransaction({ to: recipientAddress as `0x${string}`, value: parseEther(amount), }); const txUrl = await checkTransactionHash(txHash) return { content: [ { type: "text", text: `Transaction sent successfully. ${txUrl}`, url: txUrl, }, ], }; } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); const txUrl = buildTxUrl(txHash); return { content: [ { type: "text", text: `transaction failed: ${errorMessage}`, url: txUrl, }, ], isError: true, }; } } ); } - src/main.ts:27-27 (registration)Calls the registerTransferNativeToken function to register the tool on the main MCP server instance.
registerTransferNativeToken(server); - src/main.ts:7-7 (registration)Imports the registerTransferNativeToken function from the tool module.
